Active Recombinant Human IL3, His-tagged

• Cat.No.: IL3-8862H
• Product Overview: Recombinant Human IL3 was produced in the endosperm tissue of barley grain (Hordeum vulgare).

Specification

• Species: Human
• Source: Hordeum Vulgare
• Tag: Non
• Description: IL-3 (Interleukin-3, Hematopoietic growth factor, Mast cell growth factor), a pleiotropic growth factor, is mainly produced by activated T-cells, but is also produced by keratinocytes, NK-cells, mast cells, endothelial cells and monocytes. IL-3 promotes proliferation and differentiation of various hematopietic cell types, including pluripotent stem cells and more committed progenitors. IL-3 also affects activity of mature hematopoietic cells and often functions in combination with other cytokines. Human IL-3 is species-specific and shows no biological activity on murine cells.
• Predicted N Terminal: His
• Form: Sterile filtered through a 0.2 μm filter. Lyophilized from PBS, pH 7.2
• Bio-activity: The bioactivity of recombinant human IL-3 was determined by its dose-dependent effects on the proliferation of TF-1 cells. The ED50 value for this effect is typically< 0.2="" ng/ml,="" corresponding="" to="" a="" specific="" activity="" of="">5 x 10e6 units/mg.
• Molecular Mass: Recombinant human IL-3 contains 133 amino acids and a 16 a.a. histidine-based tag for a total length of 149 a.a. and has a predicted molecular mass of 17.2 kDa. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 20-23 kDa in SDS-PAGE
• Endotoxin: Endotoxin level is less than 0.05EU/μg as measured by turbidimetric kinetic assay.
• Purity: >95% by SDS-PAGE gel analysis.
• Storage: The lyophilized protein is stable at room temperature for few weeks. Reconstituted protein should be used immediately or stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile water to a concentration of no less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
